Clipping/nutrients

When should I start Clipping the top of my plant, want a bushy not to tall plant before flowering, and when should I start feeding my plant age old grow, the plant is about a week old.

the best way to get a short fat bushy plant, is to overwhelm it with light. keep the light close, and surround it with light, as soon as you move the lights up they stretch. i also keep mine on for 24/0 during veg then gradually make my way down to 12/12 for flowering, this slows down the stretching too, but it also puts off flowering for another week or 2. really depends on your size/space, and timeline.

its not really about age, its about size, and what its growing in, hydro you NEED nutrients immediatly, soil has nutrients already. you can start giving it some N heavy stuff now, just go weak, like 1/4th strength

I let it grow to 7 true nodes then cut back to the 4th I let it veg another weekk for the new tops to develop then start flowering.
